Vehicle-to-Grid (V2G) technology

Vehicle-to-Grid (V2G) technology: Kerala State Electricity Board (KSEB), in collaboration with IIT Bombay, recently launched a pilot project to assess the feasibility of Vehicle-to-Grid (V2G) technology integration with the State’s power grid to evaluate EVs' role in grid support during peak demand when solar energy is not available.

• About V2G: It allows Electric Vehicle (EV) batteries to send power back to the electricity grid.

o Function: EVs act as decentralized battery storage systems via bi-directional chargers when not in use.

• Working of V2G: Grid-to-Vehicle (G2V) -Power flows from the grid to charge the EV & Vehicle-to-Grid (V2G) - EV discharges stored energy back into the grid when required.
• Applications:

  o Vehicle-to-Home (V2H): EVs power household devices.

  o Vehicle-to-Vehicle (V2V): Energy transfer between EVs.
  
  

  • V2G Technology in India’s Power Sector

  o Peak Load Reduction: EVs discharge energy during peak periods, reducing power plant stress and energy costs.

  o Load Balancing: Charging EVs during off-peak hours helps stabilize daily electricity demand.

  o Storage for Renewables: V2G stores surplus solar/wind power and releases it during shortfalls.

  o Grid Balancing: Offers services like frequency regulation and voltage support.
